Problems solved by technology

[0004] Whether the filter material can be thoroughly cleaned and regenerated after each filtration is an important technology of filtration. The key to the difficulty of cleaning the fiber filter material lies in the nodes of the filter element. The nodes of these filter materials are consolidated relatively firmly. Under the action of external force, the material enters the gap between the fibers in a wedge shape, and here is the node at the end of the fiber. It is also difficult to clean thoroughly under the action of backwashing air and water. If the comet filter material and fiber ball filter material are not cleaned properly Thorough, easy to form mud balls, it can't be cleaned

Embodiment 1

[0017] Embodiment 1: a filter tank of 2 meters in length and width, first the fiber filter material 4 is wound into a circular fiber filter material with a circumference of 2.4 meters and a weight of 0.35 kg. The specification of the rod 3 is a DN15 UPVC pipe with a length of 2 meters ; First, tie the ends of the two tubes to the ends of the upper and lower filter plates with nylon ropes, and then put a group of wound fiber filter materials into the upper and lower rods respectively, and place them on the upper and lower rods Tie a second nylon rope at a distance of 150mm from the first nylon rope on the rod, connect the rod 3 and the filter plate 1, and keep filling the fiber filter material 4 on the rod in this way, and hang it full of fiber The distance between each tube of the filter material 4 is 30 mm. In this way the whole filter tank is filled with fiber filter material.

[0018] After trial use, the fiber filter material installed in this way has an average suspended...

Abstract

The invention belongs to the technical field of filter plant in the field of water treatment, and in particular relates to a method for installing fiber filter materials in bulk. The method comprises the following steps: directly installing two ends of the wrapped fiber filter materials without any treatment on two rods 3 in bulk, and fixing the rods 3 on a filter board 1 through a connecting carrier 2, wherein fibers on the joints of the fiber filter materials 4 and the rods 3 are distributed on the rods 3 evenly in a floating state, and are not knotted by ropes to be limited. The method greatly improves the cleaning regeneration effect of the fiber filter materials, reduces the installation time, and improves the quality and the quantity of filtered water.

Description

technical field [0001] The invention belongs to the technical field of filter equipment in the field of water treatment, and in particular relates to a method for installing bulk fiber filter materials. Background technique [0002] Fiber has been used in the field of water treatment as a filter material for filtration equipment for a long time. Compared with traditional granular filter materials, it has a series of advantages such as high filtration speed, small footprint, high filtration precision, and large sewage interception capacity. advantage. [0003] At present, the filter materials include comet filter material, fiber ball filter material and fiber bundle filter material. Comet filter materials and fiber balls are made of a bunch of very short fibers in the middle to form a node, so that the fibers do not scatter to form a filter element; the fiber bundle is to make the fibers into a bundle, and the two ends of the fiber are tied with nylon ropes. It is fixed on ...
